摘要
本论文对逆变电源的数字控制技术进行研究。相对于模拟控制,数字控制具有能够简化硬件电路设计、克服模拟电路参数温度漂移、控制灵活易于实现先进控制技术、性能可靠、降低开发周期等优点,且随着新型电力电子器件和数字处理器的飞速发展,数字控制的逆变电源应用日益广泛,成为以后电源发展趋势。
本论文在单相逆变电源电路模型的基础上建立了连续时间和离散时间域数学模型,为控制系统的设计提供了理论基础;简单介绍了正弦脉宽调制原理和单、双极性正弦脉宽调制的工作原理,分析了正弦脉宽调制下的谐波含量。文章第三章介绍了数字PID技术和离散滑模控制技术,根据双环控制的优点,用MATLAB/SIMULINK仿真软件分别建立了电压外环为PI控制和电压外环为离散积分滑模控制的单相逆变器仿真模型并进行了仿真分析。第四章构造了基于TMS320LF2407A的单相数字控制逆变电源实验平台,详细介绍了系统硬件电路设计,软件程序的实现方法。文章最后给出了单相电压源逆变电源的试验波形及其分析,实验结果表明该系统具有良好的动静态性能。

The continuous-time and discrete-time domain mathematical models based on the inverter power supply circuit model are established, which provide the theoretical foundation for the control system design in this paper; the principle of SPWM and the working principle of single, bipolar SPWM is simply introduced, the harmonic content is analyzed. The chapter 3 of paper introduces the digital PID control technology and discrete sliding mode control technology. According to the advantages of dual-loop control strategy, the two simulation models are established and simulated by MATLAB/SIMULINK Software. The voltage loop of one model is controlled by PI controller; the other one is controlled by the discrete-time integral sliding model controller. The single-phase digital controlled VSI platform is constructed. The design procedures of hardware and software program are introduced in details. Finally the experiment results about single-phase voltage inverter are presented and analyzed. The results reveal that the system has the excellent dynamic and static state performance.
